CORN-STUBBLE CUTTER.

SPECIFICATION forming part of Letters Patent No. 769,326, datedSeptember-6, 1904.

Application filed April 10, 1902.

To all whom it may concern.-

Be it known that I, JOHN H. SHARP, a citizen of the United States,residing at Columbus, in the county of Burlington and State of NewJersey, have invented certain new and useful Improvements inCorn-Stubble Cutters; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My present invention relates to that class of machines known ascorn-stubble cutters and is designed as an improvement upon a formerpatent granted to me under date of March 20, 1900, and numbered 645,693,the object of my present improvements being to provide a machine of thecharacter noted having a variety quired thereof may be properlyaccomplished.

A further object of my invention is to provide an improved machine whichis adapted for elevating and lowering the implements at tached thereto,whereby the latter are brought into contact with the soil or elevatedtherefrom.

With these and other objects in view, which will readily appear as thenature of the inven' tion is better understood the same consists of thenovel details of construction and general arrangement of parts as willbe hereinafter fully described, illustrated, and claimed.

My invention will be more fully understood by reference to theaccompanying drawings,

wherein the same parts are indicated by like letters throughout theseveral views, and in which- Figure 1 represents a side elevation of myimproved machine; Fig. 2, a bottom plan view of the same, and Fig. 3 arear view thereof.

In carrying out my invention the narrow rectangular frame Ais composedof the two side bars a a, secured at the proper distance apart by meansof the cross-bars 1) upon the front and rear ends thereof, suitablebearings being provided at the rear of said frame for the reception ofthe crank-axle B, as shown.

Beneath the rear part of the frame A and attached thereto by suitablebolts is provided a V-shapedframe D, having its point projecting towardthe front of the machine and'pro- Serial No. 102,216. (No model.)

downwardly-projecting standards G, having their lower ends bent at rightangles to receive the front cutting blade or knife H, which is securedthereto in a nearly-fiat or slightly: inclined position, as shown. Thecutting edge of the said knife or blade is set diagonally across thefront-of the machine and is preferably provided at its point with anupwardlycurved projection or guard H to deflect or clear the grass orweeds from the stubble that is to be cut. Upon the side of the frameopposite to that of cutting blade or knife is provided a guard-plate I,the edge of which is set in a reverse direction to that of the edge ofsaid knife or blade H and the object of which is to clear away the topsof the stubble as it is cut, as also to hold the same in position duringthe operation of cutting, such construction being substantially the sameas that shown in the patent previously granted me, as above noted.

The crank-axle B is provided with suitable machine-wheels B, and to oneside of the crank-axle and rigidly secured thereto is provided anupwardly-projecting lever J, having a sliding clutch J connectedtherewith, the lower end of which is adapted to engage with one of aseries of notches in the segmental arm K, attached to one side of theframe A in such manner that the said frame may be held in the "desiredposition to cause the disks to operate with the requisite force to cutand disintegrate the stubble and to properly prepare the soil for theplanting of crops and also to enable the frame to be held in an elevatedposition to keep the-disks from contact with the soil when the machineis to be wheeled to and from the field. Y

A seat L is attached to. the rear upperpart of the frame A for thereception of the driver or operator, whose weight upon the same servesto assist in holding the disks and blades 'jacent to the vehicle-pole F,are provided two down to their Work When the machine is lowered inposition for operation.

By means of my invention as herein set forth I am enabled to provide amachine of the character designated Which will be simple, compact, anddurable in construction and which Will perform the required Work in arapid and satisfactory manner.

Having thus described my invention, What I claim as neW and useful, anddesire to secure by Letters Patent, is

A machine of the character described, composed of the narrow rectangularframe A, provided with the front cutting-knife and guard, the V-shapedframe D provided with the disks E upon the front thereof and withintermediate rear disks E in line with the center of said front disks,and the segmental arm K, in combination with the crank-axle B, wheels Band operating-lever J, substantially as speci lied. In testimony whereofI aflix my signature in presence of two witnesses.
